Hey Teacher Friends,
Right now I'm in the process of creating a series of STEM projects for students who are studying Earth Science.. The first unit I'm focusing on is Weather and the Atmosphere! After doing a little research, I came up with two great STEM projects that are simple enough to create in the classroom. Initially I originally thought these projects might be TOO simple for 4th-6th grade, but they are much more difficult to pull off than they appear!
STEM Activity #1: Anemometer Challenge!
An
anemometer is an instrument that is used to measure wind speed. Some anemometer
devices can also measure the wind direction.
A
cup
anemometer has
four cups connected to horizontal arms that spin on a vertical pole. The design
was later mortified to three cups because it responded more quickly to gusts of
wind and had less errors in the reading.
A well designed anemometer should be able
to respond quickly to changes in wind speed. It should also be able to detect a wide range of wind speeds.
Here's the challenge: Using
a list of supplies, students must design an anemometer that accurately measures
wind speed. They must be able to measure how many spins the device makes per
minute by marking one of the revolving cups. They have one
hour to complete this challenge. (time testing their anemometer does not count
towards the hour). In order to test, the
anemometer should be placed outside on a windy day or can be tested with a fan. ***Check out the link below for more information about the challenge.
STEM Activity #2: Barometer Challenge!
A
barometer is an instrument that measures pressure in the atmosphere. They were
once commonly used in ships, aircrafts, and even households around the world.
There are several different types of barometers, such as the water-based
barometer, the mercury barometer, and the aneroid barometer.
Here's the challenge: Using
a list of supplies, students must design a type of barometer that measures
changes in the atmospheric pressure. Their design must have a needle that
measures an increase or decrease in air pressure. Students must use the items
listed below and they are not allowed to add items to the list. If they test it
and it does not work properly, they have two more attempts to fix their design.
They have one hour to design their barometer. (time testing their barometer
does not count towards the hour). In
order to test, the barometer should be placed outside or by a window.
